Jason Jones, 25, is charged with attempted first degree intentional homicide in connection with the stabbing at the State Office Building in downtown Milwaukee on April 10.

According to the criminal complaint, officers responded to a Duress Alarm on the fourth floor of the office building. When the two Capitol Police officers arrived, they encountered Jones in a hallway as they walked past each other.

The complaint states that as Jones passed the officers, he quickly turned around and swung twice at the right side of Officer Greg Friberg's neck. Jones then ran at the second officer before running into a stairwell and escaping.

Witnesses said that Jones had been in the office building a few days earlier, and had identified himself as Jason James or Jason Jones.

Officers compared surveillance video to still photographs of Jones and determined they were similar.

Still images from the surveillance video was shown to Jones' brother and mother, who both positively identified Jason Jones.

"He's had issues psychologically for a while, and I think that if he's on proper medication he's a great guy," said his brother, Travis. "But when he doesn't get medicated the right way, it tends to throw him off the handle."

Jones was also identified by two witnesses in a police lineup.

According to the complaint, Jones is also being charged with recklessly endangering safety in a March 16 incident.

According to the complaint, a detective saw Jones being escorted from an apartment building following the State Office Building incident, and recognized Jones from surveillance video from a March incident at a West Allis Pick N Save store.

A man making a bank withdrawal inside the store said he walked out of the building, heard footsteps and then felt a blow to the back of his head.

Once knocked to the ground, the victim saw a man attacking him with a bladed knife.

The man suffered a minor stab wound to the back of the neck, and surveillance stills matched the profile of Jason Jones.

Jones' mother and brother also identified Jason Jones in the photos from the March incident.
